1* Texas Instruments - LM3692x Highly Efficient White LED Driver
2
3The LM3692x is an ultra-compact, highly efficient,
4white-LED driver designed for LCD display backlighting.
5
6The main difference between the LM36922 and LM36923 is the number of
7LED strings it supports.  The LM36922 supports two strings while the LM36923
8supports three strings.

10Required properties:
11	- compatible:
12		"ti,lm36922"
13		"ti,lm36923"
14	- reg :  I2C slave address
15	- #address-cells : 1
16	- #size-cells : 0
17
18Optional properties:
19	- enable-gpios : gpio pin to enable/disable the device.
20	- vled-supply : LED supply
21	- ti,ovp-microvolt: Overvoltage protection in
22	    micro-volt, can be 17000000, 21000000, 25000000 or
23	    29000000. If ti,ovp-microvolt is not specified it
24	    defaults to 29000000.
25
26Required child properties:
27	- reg : 0 - Will enable all LED sync paths
28		1 - Will enable the LED1 sync
29		2 - Will enable the LED2 sync
30		3 - Will enable the LED3 sync (LM36923 only)
